本文實(shí)例為大家分享了Android實(shí)現(xiàn)圖片選擇器功能的具體代碼，供大家參考，具體內(nèi)容如下
圖片選擇功能用的是GitHub上的依賴庫，網(wǎng)址
先來看下我運(yùn)行的效果圖如下所示：
該依賴庫是Android平臺(tái)上拍照/錄像，圖片/視頻選擇，編輯和壓縮的一站式解決方案。
添加依賴，在app->build.gradle里面添加依賴
//圖片/視頻選擇、預(yù)覽、編輯與拍照implementation 'com.github.guoxiaoxing:phoenix:1.0.15'
初始化：
public class App extends Application { @Override public void onCreate() { super.onCreate(); Phoenix.config() .imageLoader(new ImageLoader() { @Override public void loadImage(Context mContext, ImageView imageView , String imagePath, int type) { Glide.with(mContext) .load(imagePath) .into(imageView); } }); }}開啟功能：
private void callUpSelecter(boolean isCamera, int type, int REQUEST_CODE) { if (TextUtils.isEmpty(fileID)) { Phoenix.with() .theme(PhoenixOption.THEME_RED)// 主題 .fileType(MimeType.ofImage())//顯示的文件類型圖片、視頻、圖片和視頻 .maxPickNumber(9)// 最大選擇數(shù)量 .minPickNumber(0)// 最小選擇數(shù)量 .spanCount(4)// 每行顯示個(gè)數(shù) .enablePreview(true)// 是否開啟預(yù)覽 .enableCamera(isCamera)// 是否開啟拍照 .enableAnimation(false)// 選擇界面圖片點(diǎn)擊效果 .enableCompress(true)// 是否開啟壓縮 .compressPictureFilterSize(300)//多少kb以下的圖片不壓縮 .compressVideoFilterSize(2018)//多少kb以下的視頻不壓縮 .thumbnailHeight(160)// 選擇界面圖片高度 .thumbnailWidth(160)// 選擇界面圖片寬度 .enableClickSound(false)// 是否開啟點(diǎn)擊聲音 .pickedMediaList(add_lists)// 已選圖片數(shù)據(jù) .videoFilterTime(0)//顯示多少秒以內(nèi)的視頻 .mediaFilterSize(0)//顯示多少kb以下的圖片/視頻，默認(rèn)為0，表示不限制 .start(UploadMorePicActivity.this, type, REQUEST_CODE); } }獲取結(jié)果：
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 889 && resultCode == RESULT_OK) {//相冊(cè) //返回的數(shù)據(jù) List<MediaEntity> result = Phoenix.result(data); Log.e("=====result==", result.toString()); add_lists.clear(); add_lists.addAll(result); adapter.updateItems(add_lists); btnOkEnable(add_lists); } else if (requestCode == 899 && resultCode == RESULT_OK) {//拍照 List<MediaEntity> result = Phoenix.result(data); add_lists.addAll(result); adapter.updateItems(add_lists); btnOkEnable(add_lists); } }recyclerView的適配基類：
